FLAT STOVE.

To @ZZ whom t may concern:

"Be it known that I, JAMES WATSON, a citizen of the United States, residing at Marinette, in the county of Marinette and State 'of Wisconsin, have invented a new and useful Flat Stove, of which the followingr is a specification.

The device forming the subject matter of this application is a folding stove of the kind ,used by campers, prospectors and others, and one object of the invention is to provide a stove ofthe kind above specified, which can be folded readily vinto small compass whennot in use.

-3' Another obj ect of the invention is to provide a reinforcement for the top. of the stove, the reinforcement serving, also, yas a baille, and being so mounted that it can be folded iiat against the top of the stove when the stove is collapsed.

Another object of the invention is to provide novel means for holding the legs of the stove in place. e Y 4 A` further object of the invention is to provide novel means whereby the stack or chimney may bey ,heldeny the stove.

. 1t is ywithin the province of the disclosure to improve generally` and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as'the description proceeds, the invention resides in the combination land arrangement of parts and in the details of lconstruction ,hereinafter `described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope ofwhat is claimed, without departing from the spirit of the invention.

Specification of Letters Patent.

Application filed January 8, 1918. Serial No. 210,906.

Fig. 7 is a perspective view showing the means whereby the legs are held in place;

Fig. 8 is a sectional detail wherein a modified method of using the stove is depicted.

The stove forming the subject matter of this application preferably is made of metal throughout, sheet iron ordinarily being employed. The stove comprises a top 1 having a depending flange 2. Side walls 3 are united by hinges to opposed portions of the flange 2, the hinges preferably being in the form of knuckles 4 receiving pivot rods 5. The side walls 3 are hinged to the flange relatively nearto the lower edge of the flange, intermediate the upper and lower edges of the liange, as an inspection of Fig. 4 will make manifest. The side walls 3 are supplied with rectangularly disposed inwardly projecting lips 6. An end wall 7 is hinged in the angle dened by a part of the flange 2 and the top 1, the hinge embodying knuckles 8 and a pivot rod 9. A vertically swinging door 10 is disposed opposite to the end wall 7 and is united by knuckles 11 and a pivot rod 12 to the eX- treme lower edge of one end portion of the iiange 2. The door 10 has rectangularly disposed side lips 14, the lower edge of the door being supplied with a bead 15. There is an opening 16 in the door 10 near the bead 15, as shown to best advantage in Fig. 4. An eye 17 on one end of a handle 18 is pivotally mounted in the opening 16, the handle being of use for opening and closing the door 10 and for propping thedoor in an open position. `When the door 10 is in a closed position, a projection 18 on the handle 18 is engaged in the ground, kthe handle thus constituting a. means for holding the door closed.

Cross rods 19 are terminally mounted in opposed portions of the flange 2 close to the top 1. Truss plates 20 are disposed beneath the top 1, the truss plates preferably tapering toward their ends as shown at 21 in Fig. 3. The truss plates 20 have sockets 22 receiving the cross rods 19,v the truss plates, therefore, being pivotally mounted so that they may hang in the depending positions shown in Figs. 2 and 3, or be turned up flat against the top 1. The truss plates 20, as their name indicates, serve to reinforce and sustain .the top'l, and further, they act as baliies for the product-s of combustion proceeding toward the due 43, hereinafter described. f

rl`he numeral 23 denotes a. pair of rear legs, which preferably are pointed as shown at 25, so that they can be driven into the ground readily. The upper ends of the legs 23 are united with the side walls 3, near to the end wall 7, by means of pivot elements 25. Figs. l, 2, and 7 will show that the legs 23 are broad enough so that they project outwardly to a slight extent beyond the end wall 7. The legs 23 are provided in their upper edges and in their outwardly extended portions with seats 26. vertically swinging latches 27 are pivoted at 28 to the end wall 7 and are supplied in their lower edges with seats 29 adapted to cooperate with the seats 26 in the legs 23. Pointed forward legs 30 are provided, and the same are united .by means of pivot elements 31 with the side walls 3, near to the vertically swinging door l0. rl`he top l of the stove is supplied, near to the end wall 7, with a draft opening 32. Flanges 42 project upwardly from the top l, about the opening 32, as seen bestin Fig. 5. rlhe top l is provided, on opposite sides of the opening 32, with eyes 33 and 38. A. locking frame 35 is shown, the same preferably being of L-shape and comprising rectangularly disposed arms 34 and 36. rlhe arm 34 is pivotally mounted, near to its outer edge, in the eyes rl`he numeral `40 denotes an L-shaped frame comprising rectangularly disposed arms 39 and 4l, the arm 39 being pivotally mounted, near to its outer edge, in the eyes 33. rl`he arms 34 and 39 of the frames are parallel to each other, and the same observation holds true with respect to the arms 36 and 4l. For a purpose to be described hereinafter, one end of the arm 34 is spaced, as shown at 37, from the top l of the stove.

rlhe numeral 43 marks a rectangular iiue which preferably is of collapsible form. rlhe flue is not described in detail, because it has been claimed in my copending application Serial No. 208,594 filed on the 24th of December, 1917, for Letters Patent on an elbow. 'lhe lower end of the iiue 43 is provided with an outstanding foot or lange 44.

When the stove is set up for use as shown in Figs. l, 2 and 3, the coperation between the various parts is as follows: rl`he walls 3 and 7 are disposed in depending relation with respect to the top l, the lips 6 on the side `walls 3 overlapping the outer face' of the end wall 7, as shown in Fig. 7. lf the door 10 is closed, the lips 14 on the door overlap the outer faces of the walls 3. rlhe legs 30 and 23 are disposed in depending positions and the latch 27 is swung downwardly until the seat 29 in the latch coperates with the seat 26 in the leg 23. rl`his arrangement accomplishes two results: first,

the legs 23 are held against swinging on the pivot elements 25; and second, the end wall 7 is prevented from swinging inwardly. rlhe truss plates 20 are disposed at right angles to the top l so as to reinforce the top and to serve as baihes for the products of combustion as the same move toward the stack 43. rlhe stack 43 is placed on the top l about the iiange 42, the foot 44 of the tlue extending outwardly. The arms 41 and 36 of the frames 40 and 35 are swung downwardly, the foot 44 on the iue being engaged by the arms 34 and 36 of the frame 35, and being engaged by the arms 39 and 4l on the frame 40. rlhe arm 4l has sutlicientl resiliency so that its free end may be engaged beneath the end 37 of the arm 34 and when the parts are arranged as above described, the flue 43 will he held securely, in upright position, on the top l of the stove.

ln order to collapse the stove and dispose the same as shown in Fig. 4, the stove is inverted, and the truss plates 2O are folded flat against the top l, it being recalled thatrthe stove has been inverted from the position of Fig. l. 'lhe end wall 7 isV swung inwardly toward the top of the stove, the side wal1s3 being swung inwardly to overlie the end wall 7, the legs 23 having been rotated en the pivot elements 25 until the legs extend longitudinally of the folded stove, as shown in Fig. 4. lt will be understood that the iiue 43 may be released from the top of the stove by manipulating the framesY 40 and 35. After the iue has been removed, it can be folded out and stored within the contour of the folded stove. The door l() is swung over on top of the walls 3, the head 15 entering between the opposed parts of the fiange 2. Fig. 8 discloses a modified way of using the stove.- ln Fig. 8, the openin 32 is closed by a plate 45 held in place by the frames'35 and 40. I'lhe ange or foot44 on the flue 43 is engaged beneath the lower edge of the end wall 7, the ue extendingunderground.

An elbow 46 is connected with the outerend of the flue, a stack 47 being mounted jonthe upwardly projecting end of the elbow; VvThe arrangement shown in Fig. 8 permitsproducts of combustion to escape beneath the lower edge of a tent wall 48, and renders it roo unnecessary to make a hole in the tent wall for the passage of the ue.

Having thus described the invention, what is claimed is:

l. A stove oomprisin a top having `a depending iiange; an en wall hinged in the angle dened by the iiange and the top; side walls hinged to the ange intermediate the lower and upper edges of the iange and having end lips overlying the outer face of the end wall; and a vertically swinging door hinged to the extreme lower edge of the iiange and having side lips overlying the outer faces of the side walls, the end wall being foldable against thel top" within the ange, the side walls being foldable within the flange to overlie the end Wall, and the door bein foldable to overlie the side Walls, the lips 0% the door overlying the outer face of the fiange when the door is folded.

2. A stove having a draft opening; frames comprising opposed arms hinged adjacent their outer edges to the stove near the opening, and oppositely disposed arms projecting from opposite ends of the hinged arms in opposite directions; and a member held by all of the arms in coperating relation to the opening.

3. A stove having a draft opening; frames comprising opposed first arms hinged adjacent their outer edges to the stove near the opening, and oppositely disposed second arms projecting from opposite ends of the rst arms in opposite directions, one end of the rst arm of one frame being spaced from the stove, and the free end of the second arm of the other frame being releasably engaged beneath said spaced end of the first arm, thereby to hold the frames against movement; and a member held by all of the frames in coperating relation to the open- 111 gIn testimony that I claim the foregoing as my own, I have hereto aliXed my signature.
